Setback Speed
Setback Speed is a reduced ventilation rate. Setback Speed is congured using
a step-less independent fan control potentiometer. The Setback Speed can be
enabled by connection of a volt-free one-way switch, or combined with the Boost
Speed with the 3 position switch TP 508.
Continuous Speed
Continuous Speed is the normal running speed of the unit. Continuous Speed is
congured using a step-less independent fan control potentiometer.

10
Boost Speed with Overrun Timer
Boost Speed is an increased speed providing higher extract air ow. Boost Speed
is congured using a step-less independent fan control potentiometer. The Boost
Speed can be triggered by any device which provides a volt-free one-way switch,
such as a PIR, thermostat, humidistat or a standard one-way switch
Boost Overrun Timer
Boost Overrun Timer maintains the Boost Speed for a specic time variable between
0 and 30 minutes. The Boost Overrun Timer time is congured using step-less
independent potentiometer.
Integrated Humidity Sensor
The units are tted with an Integrated Humidity Sensor. This continuously
monitors the relative humidity (RH) of the extracted air. The fan speed increases
proportionally between Continuous Speed & Boost Speed depending on the
measured %RH; see below for details.
The Humidity Sensor’s set point is variable from 55%RH to 85%RH and is congured
using a potentiometer.

Remote indicator panel (auralite) or control connection
The auralite remote indicator panel can optionally be connected to the unit.
auralite is a low voltage hard wired remote LED ventilation system status indicator,
designed to t a standard UK patress or recessed backbox. The indicator is for use
with specic Titon CME units. The indicator has six LEDs which display

Installation
Fixing
1. The unit must be securely xed to a
smooth at surface, any orientation
is possible.
2. Mark the four xing hole centres
using the Base as a template.
3. Drill holes for xings, use 4mm
Pan Head screws. Always use a
xing type and length suited to
the substrate type. The unit weighs
approximately 5kg.
4. Mount the Base, ensuring it is not
distorted by the xings or mounting
surface.
5. Clip the Motor and Lid assembly to
the Base, ensure that all 6 clips have
engaged.
Tighten screws by hand, DO NOT over
tighten screws or use power tools.

7. Fit two screws from the Screw Pack
through the preformed holes at the
front of the Inlet Ring to securely x
the Inlet Ring/Scroll assembly to the
Base.
8. Fit one screw from the Screw Pack
through the preformed hole in the

Ducting Connections
Titon recommend the use of guidance given in the Domestic Ventilation
Compliance Guide 2010 Edition ISBN-978 1 85946 378 9 and
Approved Document Part F 2010 ISBN-978 1 85946 370 3 for all
installations in the United Kingdom.
The above documents can be downloaded free from www.planningportal.gov.uk.
Titon recommend that:
1. 204 x 60mm ducting is used for the
connection of the Extract Port to
Outside.
2. 204 x 60mm or 110 x 54mm ducting
is used for connection to the other
ports.
3. A minimum distance of 200mm
between the CME2.1 Q Plus unit and
any sharp bends in duct work.
4. Ducting should be insulated where
it passes through unheated areas
and voids.
5. Unit should be insulated when
tted in unheated area.
6. Where a duct extends externally above roof level the section above the roof
should be insulated or a condensate trap should be tted just below roof level.
7. Where ducts pass through re barriers, they must be appropriately re stopped
in accordance with the requirements of Part B Building Regulations (England &
Wales).
8. A ducting condensate drain must be tted to vertical Extract Port to Outside
duct work.
9. Condensate drain pipe work must be adequately secured, installed to have
a minimum 5° fall and be insulated if any part of the pipe passes though an
unheated void.

10. All insulation to be the equivalent of
at least 25mm of insulating material
with a thermal conductivity
of 0.04 W/(mK).
11. Ducting must be installed in such
a way that resistance to airow is
minimised.
12. Ducting connected to the Extract
Port to Outside must be to the
external air outside the building
envelope.
13. All ducting joints including those to
the CME2.1 Q Plus unit’s Duct Ports
and Convertible Port Covers must
be permanently connected and
sealed.
14. Do not distort ducting, Convertible
Port Cover or Duct Ports.
15. 204 x 60mm ducting ts inside the
units Duct Ports.
16. 110 x 54mm ducting ts inside the
Convertible Port Cover.
17. Unused extract ports must be tted
with non-converted or undamaged
port covers.

16
How to Convert Port Cover
1. To enable tment of 110 x 54mm
ducting, modify the Convertible
Port Cover by tearing out the ‘rip
strip’.
2. When using the convertible port
cover ensure the tear out section is
completely removed.

17
Wiring Connections Access
Access to the connections for mains, boost and other volt-free control functions is
via removal of the Cover and the internal printed circuit board cover. Printed circuit
board cover must be replaced following connection of wiring.
